. DOOR.

Application fl led October 6, 1919.' Serial 1W0. 328.709.

. To all whom it may concern:

. Be it known that I, AN'rHoNY L. Cnnsor,

, a citizen of the United States, residing at Vineland in the county of Cumberland and State of lIew Jersey, have invented certain new and useful Improvements in a Door, of which the following is a specification.

My invention relates to improvements in sliding doors for buildings requiring large doorways, such as garages, and my invention partlcularly relates-to a door adapted to be used on a wall having a doorway 10- cated therein adjacent to a side wall extendingat right angles to the doorway wall and where the door, when in the open 'POSltlOIl,

' extends parallel with the side wall.

The object of myinvention is .to provide means for supporting the door by which the rear edge of the door will move in a vline parallel with the side wall and the forward edge of the door will move parallel with the doorway wall throughout a portion of the distance'and through an arc of a circle into the open position; a further.

object of my invention is to provide two separate tracks, one a straight track carrymg the rear edge of the door and the other track having a curved portion carrying the front edge of the door or the forward sections of the door if made in-sections. The said curved portion of the track having sufficient radius to allow the door'to move freely in either direction and thus permitting the door to be used in a space where there is no room for the door to have any movement parallel with the doorway wall;

a still further object of my invention is to construct a door which maybe operated by power and to provide suitable operating mechanism therefor;-a still further object of my invention-is to rovide a rigid brace for holding the rear e ge of the door vertically and for holding the bottom of the door closed against a pressure from without the building, and to provide an extension hanger or carriage for carryin the rear edge of the door and the said race and also having v'arious'other parts of the operating mechanism attached thereto; and

a still further object is to provide various other novel features of construction and arrangement of the several parts which will be more fully hereinafter described and claimed Heretofore two separate straight tracks have been used for supporting a door, the tracks positloned at right angles, also a single track having a right angle bend has been used, but these forms require force to be applied at both edges of the door to fully open or close the door.

Referring to the accompanying draw ings; Fig. 1, is a perspective view of the inside of a door embodying my invention and showing the door in the closed positlon; Fig. 2, is a horizontal section of a portion of a buildin showing the door in full lines in the c osed' position and in dotted lines in the open position; Fig. 3, is a transverse section on line 3-3 Fig. 2,

showing the inside of the door when closed;

1 represents the doorway wall havlng a doorway 3 formed therein, and 4 represents a side wallextending at right-angles to the wall 1 and located adjacentto the" said doorway 3. The sliding door 5 is arranged to close the doorway 3 and when in the open osition the door will occupy a space parallel with the side wall The front, or forward edge 6 of'the door 5,-is supported by a trolley hanger 8 having wheels 9 and lO ,whichrun upon thetra'ck 12. The hanger 8 has secured thereto ,a

vertical .rod 14', on the lower end of which I is secured a collar 15, forming-one part of a ball-bearing. The other part of the ball-- bearing consists of a rotatable plate 16 upon v whichrests the head of an eye-bolt 18, having a threaded shank 19, which passes I through the door-to which is ,adjustably'" secured by nuts 21; The eye-bo1t -18 forms a beari which supports the door upon'the rod.14. herod 14 turns freelyinthe eyebolt 18 and also in the eye-bolt 20, which latter guides the rod M-but does'not support thedoor; the door is thus free to turn upon the rod.

The rear edge 7 of the .door is supported in a similar manner upon a vertical rod 22 also carrying a be l-bearing .23 uponwhich-rests an eye-bolt 24, secured to the door andthe eye-bol s 25 and are pro vided to guide the upper portion of the door upon the rod 22 and permit the door to turn upon the rod.

The vertical rod 22 supporting the rearedge 7 of the door is carried by and is secured to a trolley hanger, or carriage 30, having rollers 31 and 32, which run upon the straight track 34 extending parallel with the side wall 4.

The" track 12, on which the hanger 8, carrying the forwardedge 6 of the door, runs, is a separate track from the track 34 on which the carriage 30, carrying the rear edge 7 of the door, runs. The track 12 extends parallel with the doorway wall 1 for a portion of the width of the doorway and then curves rearwardly, with a long sweeping curve 13. Said track 12 terminates ad acent to the straight track 34, at a suflicient distance from the doorway wall to accommodate the front trolley hanger 8 when the door is in the open position, as shown in dotted lines Fig. 2. The curved portion 13, of the track 12, is formed with a curve having a long radius which insures the front hanger 8 runningfreely upon the curved track without binding.

The rear edge 7 of the door does not require any movement parallel with the doorway wall 1, to permit the door to open and close, as the hanger or carriage 30, carrying the rear edge of the door runs-upon the straight track extending at right angles to the wall 1. operated in either direction to open or close it by applyin force to the rear edge of the door only an the front edge of the door will move freely and will be guided by the trolley 8 around the curved track 12. My improved arrangement of the tracks and door, as above described makes the door particularly adapted for operation by power actuated means, in'which only a pushing and ulling force in the same plane is practicab e.

The ban er or carriage 30 is of sufiicient length to allow a brace rod 36 to be secured to the rear end thereof, with its opposite end secured to the vertical rod 22 at a point low enough upon the door to form a rigid triangular brace for holding the bottom of the door in the closed position against the doorway wall. A roller 37 mounted upon a bracket 38 secured to the rear end of the carriage 3O bears against the under side of the track 34, on which the carriage 30 is mounted and the roller 37 will prevent the rear end of the carriage from being lifted off the track due to a pressure from without when the door is closed and the rigid brace construction willprevent the bottom of the door from being swung inwardly by wind pressure from without when the door is being opened or closed.

The brace 36 and the carriage 30 are The door can therefore be fineness hinged. to the door by the vertical rod 22,,

the door is thus permit to swing upon 'the vertical axis in relation to the carriage and brace. When power is applied to the carriage to move the door the power is distributed through the rigid triangular brace to the lower portion of the door, thus insuring the free movement of the door upon the away from the side wall; A guide or track 40 is provided which is engaged by an arm 41 upon the door. The arm 41 is rigidly secured on the lower end of the rod 22, secured on the lower end of the rod 22, which extends nearly to the bottom of the door.

The arm 41 has an angular extension 43, hav-;

ing 'aws 42 which embrace the guide 40.

e guide or track 40 is secured upon the floor, or upon the side wall 4 adjacent to the floor, and extends parallel with the side wall.

As the arm 41 is rigidly secured to the rod 22 and the rod 22,- atits upper end, is rigidly secured to the carriage 30, the arm will therefore not turn in relation to the guide 40' when the door turns upon the vertical rod 22, thus the arm 41 is prevented from bindin upon the guide or track 40.

he arm 41 and the guide 40 are so positioned as to allow the door to turn freely upon the. vertical 'rod'22'and the arm will hold the bottom of the door from swinging away from the guide 40, and away from the side wall 4, when the door is in the open position or when the door is being opened or. closed.. By providing the arm 41 with 40 may be located close to the. side wall 4, and occup a position between the door when the oor is open, and the wall 4, thus .an angular extension 43, the guideor track the motor and move the door into the closed position, in which position the electric-cir-l cuit is broken by'a switch 54, automatically opened by a cam 33 on the carriage 30. By reversin the hand switch 52 the circuit will be comp eted through the closed switch 56 and operate the motor in-a direction to open the door. "When thedoor reaches the open position, see Fig. 5, the cam 35, upon the carriage 30, engages the arm of the switch- 56 and breaks the circuit and stops the door. Upon. the carriage 30 is mounted a bracket 58. carrying pistons 59 and GOadapted to enter open ends of cylinders 61 and 62% secured in fixed positions, at.either end 0 Y the distance traveled by the carriage,'so that magnet 68, connected in the circuit operating the motor. The latch may be located so as to engage the rear ed e of the door instead of the carriage. T eobject'being to hold the rear edge ofthe door ag'ainst'movement at right an les to the doorway wall, so that the rear edge of the door cannot be forced away from said wall by a pressure from without. The front edge of the door is held a ainst the wall by the usual'form of stop p ate'70.

The door may be made in several vertical sections 72, 73 and 74, as shown in' Fig. 5,- 1 which are supported by additional trolley hangers 75 and 76, located upon the .door adjacent to the points where the sections are hinged together. The intermediate hangers- 75 and 76 are similar .tothe hanger 8, carrying the frontedge of the door, as above'described, and said hangers run upon the same track 12 as the forward han er 8. The rear edge 'of the rear section 74 o the door is carried by the trolley hanger or carriage 30, as

above described, which runs on the straight idly connected to the said bracket, and sand track 34. The rear section 74 is held in a vertical position by the brace rod 36 extending from the rear end of the carriage 30 in the same manner as the one piece. door.

The track 12 having the curved portion 13 has an extension 78, extending parallel with the track 34, a sufiicient distance to accommodate the trolley hangers 75 and 7 6, when the door is in the openposition, as shown in Fi 5. The several sections of the door are hinged together by hinges 79 and 80,

the latter being double acting hinges to ala lowthe rear section'to be carried by the trolley hanger on the straight track andthe forward hangers upon the curved track when the door is being opened or closed.
